Definitions

  • the invention relates to a device for the pneumatic feeding of a filling shaft and the like, with fiber material in flake form, e.g. Cotton, synthetic fiber material and the like, in which the fiber material is supplied by means of transport air via a transport channel, with an air collection space which is separated from the filling duct connected to the transport channel by an air-permeable intermediate wall, the air collection space having a shut-off blow-off opening for removal of the transport air flow, and a method for loading textile machines with fibers by deflecting a fiber-transport air mixture into a filling shaft, by separating the transport air from the fiber material in a filling shaft provided with an air-permeable intermediate wall, by blowing off the Transport air from an air collection space arranged behind the air-permeable partition, and - by feeding the fiber material from the lower end of the filling shaft.
  • fiber material in flake form e.g. Cotton, synthetic fiber material and the like
  • the fiber material is supplied by means of transport air via a transport channel
  • Devices of this type are required, for example, for cards and cards, in order to supply the machines with a material mat that is as uniform as possible.
  • the fibers are transported in a fiber / transport air mixture in pipelines and filled into the filling shafts assigned to the textile machines by deflecting the transport air flow.
  • the transport air of the pneumatic feed is generally discharged on a wall surface of the feed shaft, for which purpose the feed shaft is permeable on a longitudinal wall or has corresponding passages.
  • a filling shaft is arranged below the pipeline, which is separated from an air collection space by an air-permeable intermediate wall.
  • the air collector At its upper end, the air collector has an opening through which the transport air separated from the fiber material on the intermediate wall can be fed to an exhaust air line.
  • the opening can be varied in its passage cross section via a pivotable flap.
  • a pair of rollers At the end of the filling shaft a pair of rollers is arranged which feeds the fiber material from the filling shaft to the subsequent machine.
  • the opening at the upper end of the air collecting space which opening can be varied and also shut off, serves to control the supply of fiber material from the pipeline into the filling shaft by the amount of the transport air flowing out.
  • the opening which opening can be varied and also shut off, serves to control the supply of fiber material from the pipeline into the filling shaft by the amount of the transport air flowing out.
  • the invention has for its object to provide a device of the type mentioned, in which the greatest possible equalization of the fiber material distribution over the width of the device.
  • Another object is to design and design a feed chute with a permeable wall surface for discharging the transport air in such a way that the fiber material is piled up directly in the feed chute with an essentially uniform density over the width of the chute without a compulsory control device.
  • the invention relates essentially to an arbitrary opening and closing control when the transport air is removed from the air collection space, without a control program being directly or indirectly effective. It was recognized that an arbitrary locking and unlocking of the transport air in any change causes normal air conditions in the feed or filling shaft by itself. Any malfunctions in the stacking of the fiber material in the shaft are remedied automatically by the opening and closing of the transport air as it exits the air collection space, and the faster the change in closing and opening is carried out when the transport air exits. The idea of the invention therefore lies in the arbitrariness of the opening and closing of the relevant blocking member.
  • a distribution of the supplied fiber material over "the width of the shaft can be achieved with an effective equalization of the fiber density in the shaft. It a compensation of the distribution of the fiber material over the shaft width, at least roughly, is achieved, namely directly in the shaft itself.
  • the presence of a special control device as a function of measuring points on the fleece is not necessary.
  • the effect of the air flow not only serves to ensure the uniformity of the layering of the fiber flakes across the width of the filling shaft, but is also used for compression directly without the aid of additional control devices. It is a control of the removal of the transport air from the air collecting space without the need to use a program.
  • the housing forming the closed air collecting space can be divided by a vertical wall or the like.
  • This partial housing is provided with a blow-off opening for the transport air which contains a closing element.
  • the closing members on the two partial housings are advantageously mutually evident and closable. In this way, a certain pumping effect is obtained, and only through the jumping distribution of the air flows in the shaft.
  • the housing forming the closed air collecting space can be divided by vertical walls into a predetermined number of chambers, each chamber being provided with a blow-off opening containing the closing element.
  • a predetermined time control for the closing members need not be carried out. It is sufficient that the alternation of closing and opening is carried out over the width of the shaft without a program. If the escape of the transport air in a housing section is prevented, the fiber material held on the air-permeable intermediate wall falls downward from the intermediate wall, so that normal air conditions can be restored.
  • the irregularity of the opening and closing of the closing elements leads to the unexpected result that the fiber material reaches the layering evenly across the width and depth of the shaft without disturbances. This also results in an essentially uniform compression of the fiber material in the feed or filling shaft.
  • the fiber flakes in the filling shaft are compressed to a high degree in the upper region of the filling shaft by the transport air stream flowing through them and in combination with a pulsating vibration in the filling shaft with regard to their filling level Equalized over the width of the device in such a way that the fiber mat fed to the lower outlet of the filling shaft of the subsequent machine has a high uniformity with regard to the fiber density over its width and length.
  • the alternating closing and opening of the blow-off opening in the air collecting space leads to a pulsation which also prevents the fibers from adhering to the air-permeable intermediate wall and thus clogging of the intermediate wall.
  • the air flowing into the air collection space is suddenly prevented from escaping through the blow-off opening, so that a pressure build-up arises in the air collection space, which is also transmitted through the intermediate wall into the filling shaft.
  • the compressed air flow stops the compression effect in the upper part which is closed on all sides of the filling shaft is interrupted for a short time, which, supported by the pressure build-up in the air collecting space and filling shaft, results in a short lifting of the fiber flake column in the filling shaft. In this way, a compression and a pulsating vibration are alternately produced, which bring about an equalization of the fiber material column over the entire width of the device.
  • An important advantage of the device according to the invention is that it has a simple, inexpensive construction which also ensures a low susceptibility to malfunction.
  • the air collection space is divided into chambers vertically and orthogonally to the filling shaft with at least one air-impermeable partition wall and that at least one shut-off blow-off opening is arranged at the lower end of the chambers for each chamber.
  • the subdivision of the air collection space into chambers has the advantage, for example, that when the respective blow-off openings are shut off, pressure equalization cannot take place immediately over the entire width of the air collection space and the filling shaft, which increases the pulsating vibration.
  • the discharge openings are arranged on the side of the chambers.
  • the lateral arrangement of the blow-off opening enables the connection of suction channels with which the transport air can be supplied to the card suction, for example, without great design effort. Provision can also be made to arrange the blow-off openings in the bottom of the chambers.
  • the arrangement of the blow-off openings in the floor of the air-collecting space divided into chambers has the advantage that the transpiration air flow is only interrupted at the lower end of the filling shaft.
  • a control overlaps the alternating closing and opening phases of the blow-off openings.
  • the overlapping control has the effect that, for a short time, no transport air flow is blown out of the chambers of the air collecting space 5, as a result of which an increased pressure build-up and thus an increased pumping effect is generated.
  • the partition can consist of a mesh screen. Due to the strong pumping effect from the air collecting space, the fibers advantageously do not get caught in the intermediate wall even when a mesh screen is used as the intermediate wall.

  • a constant and constant movement of the closing element 15 at the blow-off opening 6 of the transport air has a very effective influence on the air flow in the shaft 2.
  • the air 16 exits the blow-off opening 6 through the permeable partition 9 into the air collecting space 1. This can cause the fiber flakes to adhere more or less to the permeable intermediate wall 9 until the pile of fibers has become so large that it falls off under its own weight.

This applies both to a natural discharge of the transport air and with the support of a suction train or the like.
  • a constant opening and closing of the blow-off opening 6 results in a pulsating effect of the air flow of the transport air in the shaft. Disruptive influences in the even distribution and settling of the fiber flakes in the shaft are avoided from the outset.
